The purpose of this study is to assess the safety and effectiveness of the Artisse™ Intrasaccular Device in the treatment of unruptured and ruptured wide-neck bifurcating intracranial aneurysms.
Subject or subject's Legally Authorized Representative (LAR) has provided written informed consent using the Institutional Review Board/Ethics Committee (IRB/EC) approved Informed Consent Form (ICF). Health Insurance Portability and Accountability Act (HIPAA)/data protection authorization has been provided and signed by the subject or subject's LAR.
Subject is 18-75 years of age at the time of consent.
Subject has a single unruptured or ruptured IA requiring treatment. If the patient has an additional IA, the additional IA must not be deemed to require treatment within 1-year of the index procedure.
Saccular morphology
During treatment planning, it is determined that subject may need an adjunctive implant device in addition to the Artisse™ Intrasaccular Device. (Subjects who need unplanned adjunctive implant devices are not excluded.)
Subject's target aneurysm was previously treated with other devices/implants (e.g., coils) or parent artery has a stent or other obstruction that could interfere with the correct placement of the Artisse™ Intrasaccular Device.
Subject has a known active systemic bacterial infection.
Subject has anatomy or physiology considered unsuitable (e.g., vessel anomaly or disease) for endovascular treatment with the Artisse™ Intrasaccular Device by the treating physician.
